Which slug, hypothetical ?

Centercut · Dec 13, 2020

I’ve been considering this question, and have reasons for going either way., but have decided on one over the other...

if hunting for ground squirrels at up to 250 yards, and I have two slugs that shoot equally accurate at 100 yards, MOA or better.. .25 caliber. Both are stable out to 250 yards.

JSB KO 33.5 gr slug at1000 FPS, BC of 0.092

or

NSA 43.5 gr slug at 900 FPS, BC of 0.105

Assuming cost per shot is about the same, which do you choose and why?

IMO the slug as it is going to perform better at that longer range.

frank320 · Dec 13, 2020

All else being equal, I would pick the slug with the better BC.

Similar to my long range powder burners that I take out to well over 1200 yards or more, a better BC results in less windage corrections and less variability on windage on even minute wind changes between shot to shot.

I have been reading your posts, since you started posting here. I know, like a lawyer, that you only ask questions that you already know the answer to. You know your way around Strelok, so nobody is going to surprise you with any numbers either. With that said, if taking out animals is involved, and not target shooting, always go heavy is my personal rule. I have always liked the results better.

If the conditions are generally windy, the one with the higher BC...in spite of the fact they are not dramatically different in this case.

Otherwise I’d favor the higher velocity to afford a bit more allowance for ranging error. That difference will become smaller as distance increases so it’s not as though this one is a clear differentiator either.

All math aside I’d go with NSA out of patriotism and principle of supporting a no hype only consistent well oiled out the door next day respond to your emails business.

I would shoot the NSA.

1. Support small business.

2. I would imagine the BC of the NSA results in at least 1.5 mil less holdover at 250 yards.

That said, I agree with the above that you probably did not ask a question for which you don’t already have the answer

So what do you shoot and why?

Maybe he is testing us less knowledgeable shooters?

Whichever one that gives consistently tighest groups within humane kill zone at 250 yards in that particular gun regardless of BC.

The heavier one ‘cause it’s the American way!

Maybe an Oledawg can learn new tricks?

I’ll post the numbers if anyone is interested when I get home from practice, but @nervoustrig has the most logical answer. Plus you guys that said support NSA get bonus points...

Basically in light wind less than 5 mph steady (not swirling) like early AM when it’s very calm the lighter slug. For most real world conditions the heavier slug wins out, and is what I am shooting.

Centercut · Dec 13, 2020

My rationale. With little or no wind, your major concern is elevation. All the numbers are based on a 50 yard zero.

For the light slugs, the drops at 245, 250, and 255 are 102, 107, and 113 inches for an 11 inch differential near to far.

For heavy slugs those same numbers are 122, 128, and 135 for a 13 inch differential.

So the ranging differential is about 2 inches, with the light slugs coming out on top. So if wind drift were not taken into consideration, this would be the obvious choice.

However, for a 10 mph side wind, the drift numbers are 27 inch light, and 24 inch heavy, giving the heavy slug the advantage in this case.
Conclusion: if you can get an accurate range to your target, and the wind is more than just a light breeze, the heavier slug edges out the lighter one, plus it carries more energy to the target, 42 fpe compared to 35 fpe.

The heavier slug because of the retained energy over distance.
